Developer Docs React4xp Refactored Pages

Custom pages

Content types are nice, but letting the editor compose his on pages is even better.

This is where the real power of React4XP comes into play, by defining a page, editors may drag’n drop cms components into the page!

Task: Set up page rendering

Content types need to exist in Enonic before an editor can create content. Similarly, page components must be defined before Content Studio can enable editors to create pages.

Add a page component to the app:

/src/main/resources/react4xp/components/page/Page.tsx

import {Regions,} from '@enonic/react-components';
import React from 'react'

export const Page = (props: any) => {

    return (
            <Regions {...props} />
    );
};

Add a page processor to the app:

/src/main/resources/react4xp/components/page/PageProcessor.ts

import {PageComponent} from "@enonic-types/core";
import type {ComponentProcessorFunction} from '@enonic-types/lib-react4xp/DataFetcher';

export const pageProcessor: ComponentProcessorFunction<'com.enonic.app.hmdb:main'> = (props) => {
    const component = props.component as PageComponent;

    const regions = component?.regions || {};

    return {
        regions,
        name: "main"
    };
};

Style the page component:
/src/main/resources/react4xp/components/page/Page.module.css
```
.page {
  padding-bottom: 0;
  margin-bottom: 0;
  display: flow-root;
}
```

Fetch the data:

/src/main/resources/react4xp/dataFetcher.ts

import {DataFetcher} from '/lib/enonic/react4xp';
import {commonProcessor} from '/react4xp/components/common/CommonProcessor';
//import {helloProcessor} from './components/hello/HelloProcessor';
import {personProcessor} from './components/content/PersonProcessor';
import {pageProcessor} from './components/page/PageProcessor';

export const dataFetcher = new DataFetcher();

//dataFetcher.addContentType('portal:site', {processor: helloProcessor});
dataFetcher.addCommon({processor: commonProcessor});
dataFetcher.addContentType('com.enonic.app.hmdb:person', {processor: personProcessor});
dataFetcher.addPage('com.enonic.app.hmdb:main', {processor: pageProcessor});

Register the page component in the component registry(and remove the old hello component):

/src/main/resources/componentRegistry.tsx

//import {Hello} from './components/hello/Hello';
import {Factbox} from '/react4xp/components/macro/FactBox';
import {Page} from '/react4xp/components/page/Page';
import {ComponentRegistry} from '@enonic/react-components';
import {Person} from './components/content/Person';

export const componentRegistry = new ComponentRegistry();

//componentRegistry.addContentType('portal:site', {View: Hello});
componentRegistry.addContentType('com.enonic.app.hmdb:person', {View: Person});
componentRegistry.addMacro('factbox', {View: Factbox});
componentRegistry.addPage('com.enonic.app.hmdb:main', {View: Page});

Now you can create pages!

Task: Create your first page!

It is time to build a custom page.

Turn the landing-site into a page

Before we can continue we need to remove the hello component from the componentRegistry and dataFetcher.

From Content Studio, select and edit the /hmdb content item. From the edit view, activate the page editor by clicking the monitor icon in the top right corner.

Now you can edit pages:

Now that we have a page component with a single "dropzone" inside (the region we specified earlier). We can give it some content.

Use the text component

Content Studio ships with a built-in Text component which can be handy when composing pages.

From the Insert tab (on the right hand side), drag a Text component into the region.
Text mode will now be activated, and you can use the rich-text editor to write and format text, but also insert images.
You may also click the Preview button in Content Studio for a full screen version.

That concludes the introduction to page rendering, coming up we’ll add some configurable page components to play with using parts.
